Please remember that this is the third, not the second, Linux-based
phone stack for the Neo1973.
Sun, at JavaOne in May, showed a working prototype of a Linux-based Java
phone stack running on the Neo1973. There are many pictures of this on
the web (look in the Press page on the OpenMoko wiki). The Java stack is
based on "JavaFX Mobile" about which there are not many details- it is
based on Sun's acquisition of Savaje technology - but there is a
promise that it, too, will be GPL'd in good time.
